The superiority of a wooden sword or a golden sword depends on the specific context and purpose. Here are a few considerations:

1. Functionality: In terms of practicality and functionality for combat or training purposes, a well-made wooden sword (such as a bokken) is generally superior. It simulates the weight, balance, and handling characteristics of a real sword, allowing for safe and effective training without the risk of injury posed by a metal blade. Wooden swords are commonly used in martial arts disciplines for training, developing technique, and practicing swordsmanship.
2. Symbolism and aesthetics: A golden sword may have symbolic or decorative value due to its association with wealth, prestige, or ceremonial purposes. It could be a valuable artifact or a representation of status or honor. However, in terms of functionality and practicality for combat or training, the material of the sword is more important than its appearance.
3. Durability and maintenance: A well-made wooden sword can withstand regular training and use, but it may require occasional maintenance and care to preserve its condition. A golden sword, depending on its composition and craftsmanship, could be more susceptible to damage, requiring delicate handling and maintenance to preserve its appearance and value.

Ultimately, the choice between a wooden sword and a golden sword depends on the intended use and purpose. If you are looking for a functional training tool for martial arts or combat practice, a well-crafted wooden sword would be a more practical choice. However, if you are considering symbolism, decoration, or display purposes, a golden sword may hold more significance or appeal.
